PowerShell script to detect CWA version and notify end user
If you are running Microsoft Teams in a Citrix environment you know you need to have the correct version of the Citrix Workspace App (CWA). If the version is to old users don’t have an optimized Teams and so Audio/Video will not be great and more server resources are being used.
This PowerShell script will help you with that issue. You can add it to the logon script or use it to startup Teams. (then you need to tweak it a little bit though).

Yes, you need to run it IN the HDX session.
